On the Relation Between Blood Group Genes and a Lethal Gene for Hairlessness and Prolonged Gestation
The present report deals with the occurrence of hairless calves in connection with prolonged gestation periods in the isle Hailuoto in the Northern Finland (65th latitude), about 30 km. from the continent. A total of 12 hairless calves were observed in inbred matings of a bull Saku, brought from the continent. Because this occurrence of hairless calves in a geographically isolated area was co clear-cut, it was investigated more closely, and the possible relationship of the presumably recessive lethal gene to the blood group genes was studied. The finding of an association between a recessive lethal gene and a dominant marker gene would be of practical importance for future detection of lethal carriers and of theoretical interest from the viewpoint of mapping bovine chromosomes.
